and Aix-les-Provence. The highest point of elevation in the race was at the summit of the Col d'Izoard mountain pass on stage 17. Race overview The first stage was won by André Darrigade, one of the best sprinters of that time. In the third stage, a small group escaped and finished with a margin of fifteen minutes; Gilbert Desmet became the new leader. The time trial of stage four was won by Gaul. In the second part of the fourth stage, Roger Hassenforder escaped, and a took a group with him, including Darrigade. Desmet was not in that group, and lost more than 15 minutes, which made Darrigade leader again. In the seventh stage, the peloton broke in two, and a large group of 31 cyclists finished more than 18 minutes ahead. This group included Roger Walkowiak, who had also been in the escaped group in the fourth stage, and became the new leader. Walkowiak's team manager, Sauveur Ducazeaux, advised Walkowiak that it would be too tough to try to remain the leader for the rest of the race, and suggested that Walkowiak lose the first place, and aim to regain it later in the race. In the tenth stage, Walkowiak lost time, and Gerrit Voorting who had also been part of the large breakaway group in stage seven, became the new leader. Voorting lost the lead in the next stage to Darrigade, who himself lost the lead to Jan Adriaensens in the twelfth stage. In the fifteenth stage, the entire Belgian team was weak. Most Tour followers thought it was due to a doping practice that went wrong, but officially it was attributed to food poisoning. Adriaensens lost more than nine minutes, which made Wout Wagtmans the new leader. During the seventeenth stage, there was yet another escape, which included leader Wagtmans and Walkowiak, in fifth position in the general classification. The riders in second, third and fourth place were not in the escape, so Walkowiak moved up to the second place, more than four minutes behind Wagtmans. The eighteenth stage was the last chance for the climbing specialists to win back time, and so Gaul, Bahamontes and Ockers were aiming to win back time. Gaul escaped, and won the stage alone, with Ockers in second place. During the last climb, Bahamontes dismounted and threw his bike down the ravine, wanting to stop the race. The Spanish team was
